FB_STOR (FB_STORI, FB_STORR)

5.1.1

Description

Object properties
The following table shows the object properties of FB_STOR:
FB_STOR
Area of application
The "FB_STOR" block provides the storage location parameters (attributes) available in the
user archive in the AS and transfers the actual values in the AS to the user archive.
On the basis of the "FB_STOR" block, the APF Engineering Tool generates the "FB_STORI"
and "FB_STORR" blocks for displaying format-related numerical values.
Startup characteristics
The "FB_STOR" block is called from the startup OB upon CPU startup. This call is configured
during CFC configuration by the CFC editor. Internal data and outputs are reset upon startup.
Program execution starts once the "RUNUPCYC" cycles have elapsed.
During startup, the output "QRUN_UP" = 1.
Time characteristics
The block must be called from a cyclic interrupt OB. The CFC editor enters the sampling time
of the block in the "SAMPLE_T" parameter.
Communication
Data exchange with the "FB_UA_RM" communication block on the AS level is performed via
the "UDT_UA_R_REQ_ST" (request) and "UDT_UA_R_ST" (feedback) structures. Data
exchange with the "FB_UA_WM" communication block is performed via the
"UDT_UA_W_REQ_ST" (request) and "UDT_UA_W_ST" (feedback) structures.
A read or write request can be sent to the block via the "FB_STOR_ED.pdl" process picture.
The process picture writes the "OP_REC_R" input parameters when a storage location is saved
